JOEL B. CHURCH-ILL, OF LAKELAND, LOUISIANA.

FEED-WATER HEATER AND FILTER.

SPECIFICATION forming part of Letters Patent No. 426,918, dated April29, 1890.

Application filed February 3, 1890.

To all whom it may concern:

Be it known that I, JOEL BIRMINGHAM CHURCHILL, a citizen of the UnitedStates, residing at Lakeland, in the parish of Point Coupee and StateofLouisiana, have invented certain new and useful Improvements in aCombined Filter and Feed-Tater Heater; and I do declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to an improvement in acombined filter and heater.in which a coil placed within an extended heater is made to Operate inconjunction with an overflowpipe and filter-chamber placed within theheater; and the objects of my improvements are to provide a device thatwill filter and heat water outside of a boiler by use of theexhaust-steam. I attain these objects by the mechanism illustrated inthe accompanying drawing, in which the figure is a side view of myimprovements with the wall of the heater broken away to show theinterior.

In constructing my device I take an external heater, as shown by A, andwithin this heater I place a coil of pipe, as B, and upon one end ofsame I attach a perforated pipe 0, which extends under filtering-plateD, said plate forming the base of a filtering-chamber, and in which isplaced filtering material E, and over which is placed perforated plateF, in which there is a man-hole G, and just over same and within theheater A is a manhole H. p

S indicates a partition between the filterchamber and theheating-chamber.

Leading from the filter-chamber is the pipe J, one end of which entersthe side of heaterA;

Within the shell A is placed an overflowpipe L, said pipe being placedwithin the pipe M and extending upward to within a few inches of the topof pipe M.

Connected to pipe M and extending beyond the heater A is an air-pipe N.

0 indicates manifold pipes, through which flows the exhaust-steam fromthe pumps and engine andwhich heats the unfiltered water as it flowsthrough the pipes B within the Serial No. 339,080. (No model.)

heater and the filtered water as it flows from pipe J into the heater.

K is an outlet-pipe through which the filtered water flows to theboilers.

P indicates an exhaust-pipe, which can be used for the escape of thesteam if the water should become warmer than is necessary. I

Q is a pipe admitting steam when it becomes necessary to clean out thefilteringchamber.

R is a blow-out pipe for cleaning filter.

Near one end of the heaterA, I placea gage, as shown by T, and in theend 'of said heater is a man-hole, as shown by U.

The mode of operation is as follows: The pipe B is connected to a tankor other reservoir from which the unfiltered water is drawn and flowsthrough the coil and through perforated pipe {(2, thence throughperforated plate F, and passes through pipe J into heater A ina'filtered condition, being heated in its passage by exhaust-steamflowing through pipes O and the water rising within the heater andwithin the pipe M until it reaches a point indicated by arrows,.when itoverflows, and by means of air-pipe N all siphoning is prevented. Theheated and filtered water is fed to the boilers by means of pipe K.

A striking advantage of my invention is that no space is taken up byplacing filters within the boilers, the water being fed to the boilersin a filtered and heated condition, and the exhaust-steam is utilized.

Having described my invention, what I claim, and desire to secure byLetters Patent, is

In a combined filter and heater such as described, the coil B, placedwith the heater,in combination with the overflow-pipes L and M, theair-pipe N, for preventing siphoning, the manifold pipes O, for theintroduction of exhaust-steam within the heater, the exhaustpipe P, andfeed-pipe K, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOEL B. CHURCHILL.
